Abstract
Mega-Solar generation is becoming one of the important parts in the global energy supply with the current situation of the fossil fuels exhaust and replacement of nuclear power energy after the nuclear power plant incident caused by the Great East Japan Earthquake and tsunami on March 11,2011. The CO 2 emission must be also reduced based on the Kyoto protocol. One of the effective ways to reduce the CO 2 emission is to use renewable energy such as wind and solar. For this reason, how to make optimal allocation of large-scale PV and wind farms with maximum power becomes necessary for Japan and the rest of the world. In this study we are focusing on Mega-Solar issue for the flat and angled lands. As different slope directions will affect the Maximum Point Power Tracking (MPPT) of each PV systems. We also consider the MPPT for these angled lands. So far, Mega-Solar farms are installed in flat lands. However, recently, there are a great needs (more than 1000 projects are waiting to run) for introducing Mega-Solar farms not only in flat but also in hills or angled lands. These lands with slope are no longer omitted from the planning of a Mega-Solar farm. In this paper, we consider a Mega-Solar farm which combines flat and angled lands and solve the Maximum Power Point Tracking (MPPT) of PV, cost and environment issues. In this study, for analysis the slope directions and site selection, the Geographical Information System (GIS) technique is used. Maximum Power Point Tracking (MPPT) using Perturb and Observe (P&O) Mega-Solar components are all designed on MATLAB/SIMULINK environment. One of the unique points of this study is to use the lands located near the area where affected by the radiation. These lands cannot be used for living and agricultural activity, however, it is suitable for use of a Mega-Solar farm. The targeted site was a golf-course which we are planning to install about 20[MW] solar farm.
